Hookah Market? Shipping costs?

I'm fairly new, but was looking to sell on ebay in the hookah martket...I checked on here and seen there were 2 listed suppliers...One seems better than the other but they cannot calculate shipping costs without first pulling the order....how do I know what to charge for the item to cover the "Fee Shipping" for my customer. I guess i'm rather stuck because I was planning on dropshipping but these competitors offer similar products at a fraction of what i'm listing them...

In regards to setting your shipping price, there really is absolutely no way of knowing without the supplier telling you. I find their attitude quite bizarre and I would like to pass this onto admin for a follow up with them regarding this. Just let me know who they are and we'll see what on earth the issue is with them.

The second part of your question seems to focus on price. If you are finding competitors that are selling what you are trying to also sell, but at a fraction of your sale price, then that's certainly an issue. How much research have you actually done on the market so far?
